re: Which button would you press?

Orange or Blue.

I would never want to know what people are thinking, I have no desire to sneak around on people by shapeshifting or being invisible, purple is like orange or blue, transport related, but not as effective over long distances. Purple is more of a convenience.

Imagine your life as it is now, but without the need to spend much waking time actually transporting yourself from one place to another. You'd gain like a 10% advantage over every other person.
